Concise problem statement:Audio peaks vanished when Zooming in the Timeline with Mouse/Keyboard. Peaks are simply disappear, reopening the sequence doesn't help. I have to restart the Project/App in order to obtain the peaks. Sometimes setting Audio Gain forces to redraw Audio Peaks.

Steps to reproduce bug:

1.Create a New Project

2.Import there 200 clips

3.Create a Sequence

4.Overlay Clips into the Sequence to 2 Audio Tracks (audio from 2 sources).

5.Zoom with Keyboard and Mouse

Results:Disappearing Peaks

Expected results: that wasn't an issue in earlier versions (CS5.5 and older)

It is possible that the CPU Q8300, 8 Gb RAM and the GPU GeForce 275 are the case of malfunctioning, but I wasn't in need to upgrade in earlier CS5.5 - there wasn't this issue. How about editing on a notebook with similar system? Or you want to say that notebooks should not be used for editing in Premiere Pro?

The Hardware is not the case here, it is a Fault in Premiere Pro CS6 Code.

I had a larger project with Microsoft DV AVI sources and there was everything fine.

The problem is with handling the sources, now it depends from codec or container or whatever.

Here's the Properties of the m2t/mpeg files I'm working with (gathered with MediaInfo tool):

It's so regrettable that I have to convert sources of each project into a "native" avi/mov format so that the peaks will show normally instantly as in CS5.5 and older versions. So much troubles, this is one of the reasons to think about downgrading to CS5.5.

Dude, you may want to wipe your system and reinstall everything from Windows on up. You seem to be having a LOT of issues that I can't reproduce on two different systems.

But all in all, thank you Jim for downloading the sources and confirm the bug, you can count on me too.

Originals are doesn't matter, they were converted with AME to a compressed format and downloaded by a freelancer (me):

You can produce such files by yourself if you wish, if you still untrusty

You had to download the files to believe me, huh

Redraw problems are constant and after a long period of working time only a restart remains to force redraw.

Currently I have to convert the sources in each project with AME to DV AVI so that it will work like it should, without delays, instantly, on-the-fly, real-time, troubleless, hardware-system-software-drivers-independently

It is a bug, cs5.5 and older didn't have that glitch with compressed mpeg files, the bug is already filed 2 weeks ago and hopefully fixed in an upcoming bugfix release
